There are numerous applications in which we use Video Communication, but the video size always remains one of the major difficulty associated with it as it increases the cost & bandwidth required to transmit the video . Based on the requirement most of the video recording does not need to be record everything, it requires only less information compared to a normal video therefore in order to save the storage requirement and time to visualization of the video, to do so it is need to remove non informative. Time lapse technique is a video generation technique in which each and every frame is capture and stored after some time interval. This time interval or frame selection can be based on a time period the framing device or difference between successive frames, based on that time lapsing is different for periodic or non periodic event. . If event is periodic or certain than we can use periodic time lapsing in which record each and every frame after a fixed duration of time. Differential Time Lapse video is a non periodic time lapse technique in which video generation of by capturing each frame and comparing with the previous stored frame. This can be achieved by different methods like pixel to pixel bit mapping, edge detection or motion detection. These are the methods for the frame section. Differential time lapse video does not give the information about at which time the event is occurred so in order to find the same in the video output loss less visual watermarking can be used. In this paper MATLAB based algorithm is used for generating the differential time lapse video where frame selection criterion are based on bit mapping algorithm and different edge detection techniques along with the date and time stamping using the loss less visual watermarking.
